[0002] Currently, the loading of solid catalysts in industry has achieved mechanized automation, and many industrial catalysts have adopted dense-phase loading. Dense-phase loading is a method of effectively distributing catalyst material by conveying it from the top of the reactor to a feed tray via a distribution pipe, and then distributing the catalyst material to each bed layer via a rotating feed tray. Dense-phase loading results in a more radially uniform and axially compact catalyst bed within the reactor, playing a crucial role in fully utilizing catalyst performance, increasing the throughput of the catalytic converter, ensuring the safe and stable operation of the catalytic converter, and extending the operating cycle of the catalytic converter.

Obviously, the described embodiments are some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0037] The catalyst loading cloth stabilizing frame and the catalyst cloth distribution device of the present application will be described below in conjunction with Figures 1-9 As

[0038] and Figure 1 and Figure 2As shown, the catalyst loading cloth stable frame 100 provided by the embodiment of the present application comprises a lifting frame 1, at least three foot supports 2 and at least three driving mechanisms 3; the lifting frame 1 is used for hoisting connection to the hoisting device 400, and the bottom side of the lifting frame 1 is used for mounting the cloth distributor 300; the above-mentioned at least three foot supports 2 are arranged at intervals around the outer periphery of the lifting frame 1 and are rotationally symmetrical relative to the central axis of the lifting frame 1, one end of the length direction of the foot support 2 is movably connected with the lifting frame 1, and the other end is a free end; the above-mentioned at least three driving mechanisms 3 are all arranged on the lifting frame 1 and are connected with the above-mentioned at least three foot supports 2 one by one, the driving mechanism 3 is used for driving the connected foot support 2 to rotate relative to the lifting frame 1, so as to switch to a folding state or an opening state; in the folding state, the foot support 2 is folded to the outer periphery side of the lifting frame 1; in the opening state, the free end of the foot support 2 is away from the lifting frame 1, and the free end is used to abut against the inner wall of the reactor 500.

[0039] The core of catalyst loading is to realize uniform loading of catalyst in the loading process, controllable loading density and improved loading efficiency, and more importantly, to improve the safety of the catalyst loading operation process.

[0040] In the embodiment, the catalyst loading and distributing frame 100 is connected to the hoisting device 400 below through the hoisting frame 1. For example, the hoisting device 400 can be a winch arranged near the uppermost tray of the reactor 500, the lower end of the steel cable of the winch is connected to the hoisting frame 1, and the hoisting frame 1 plays a lifting role, so as to hoist and place the catalyst loading and distributing frame 100 in the reactor 500 and enable the lifting movement. The distributor 300 is installed to the bottom side of the hoisting frame 1, that is, the distributor 300 is connected below the catalyst loading and distributing frame 100. For example, the distributor 300 can be a seed tray, the distributor 300 is connected with the distribution pipeline 200, the distribution pipeline 200 is used for supplying the catalyst material to the distributor 300, and along with the lifting movement of the catalyst loading and distributing frame 100, the distributor 300 moves up and down in the reactor 500, so as to realize the automatic loading and distributing function of the catalyst. At least three foot supports 2 are arranged at intervals around the outer periphery of the hoisting frame 1, each foot support 2 is movably connected with the hoisting frame 1, and each driving mechanism 3 is used for driving the connected foot support 2 to rotate relative to the hoisting frame 1, so that the catalyst loading and distributing frame 100 forms a foldable structure, and the catalyst loading and distributing frame 100 can be switched between the folded state and the unfolded state. When the catalyst loading and distributing frame 100 is in the folded state, all the foot supports 2 are folded to the outer periphery side of the hoisting frame 1, can be closely attached to the distribution pipeline 200, and the catalyst loading and distributing frame 100 as a whole can enter the inside of the reactor 500 through the entrance at the top of the reactor 500. When the catalyst loading and distributing frame 100 is in the unfolded state, the free end of each foot support 2 is away from the hoisting frame 1, and the free end of each foot support 2 is abutted against the inner wall of the reactor 500. In the process of lowering the catalyst loading and distributing frame 100, the hoisting frame 1 can be stably supported, and the hoisting frame 1 is prevented from shaking, so as to play a stabilizing role when the distributor 300 distributes, realize stable seed distribution, realize effective control of the stability of the distribution pipeline 200, and avoid interference on the seed distribution effect due to the shaking of the distribution pipeline 200. Meanwhile, all the foot supports 2 are rotationally symmetrical relative to the central axis of the hoisting frame 1, so that the distance from the free end of each foot support 2 to the central axis of the hoisting frame 1 is equal, the hoisting frame 1 can be stably supported at the central axis position of the reactor 500, the distributor 300 distributes more uniformly, and the loading effect is better.

[0041] The catalyst loading cloth stabilizing frame 100 of the present application is provided with the foot support 2 and the driving mechanism 3, and is of a foldable structure. During the process of lowering the catalyst loading cloth stabilizing frame 100 to a deeper position inside the reactor 500, the free end of the foot support 2 abuts against the inner wall of the reactor 500, which can stably support the lifting frame 1, avoid shaking of the lifting frame 1, and further avoid violent swinging of the cloth pipeline 200 along with the operation of the cloth distributor 300, so as to effectively control the stability of the cloth pipeline 200, stabilize the cloth distribution of the cloth distributor 300, realize stable cloth distribution, avoid interference of the cloth distribution effect caused by the shaking of the cloth pipeline 200, and more uniformly distribute the cloth, effectively ensure the catalyst loading effect, and solve the defects in the prior art that the cloth pipeline will violently swing along with the rotation of the distribution disc, which greatly affects the agent loading effect.

[0042] Specifically, the at least three foot supports 2 are uniformly arranged at intervals of an equal angle around the outer periphery of the lifting frame 1, so as to symmetrically and uniformly distribute the contact force of the lifting frame 1 with the inner wall of the reactor 500. For example, the three foot supports 2 are connected to the lifting frame 1, and the included angle between the adjacent two foot supports 2 is 120°.

[0043] Specifically, as shown in Figure 1 and Figure 3 , the lifting frame 1 comprises a foot support base plate 11 arranged at the bottom end of the lifting frame 1, and the at least three foot supports 2 are all connected to the foot support base plate 11. The outer periphery of the foot support base plate 11 is provided with a connecting lug 111, one end of the foot support 2 is rotationally connected to the foot support base plate 11 through the connecting lug 111, and the rotation plane of each foot support 2 is coplanar with the central axis of the lifting frame 1.

[0044] Specifically, as shown in Figure 1 and Figure 4 , the foot support 2 comprises a foot support body 21 and a roller 22. The foot support body 21 extends along the length direction of the foot support 2, one end of the foot support body 21 is rotationally connected to the lifting frame 1, and the roller 22 is rotationally arranged at the other end of the foot support body 21. The roller 22 constitutes the free end of the foot support 2 and is used for rolling against the inner wall of the reactor 500.

[0045] In the embodiment, the roller 22 is arranged at the free end of the foot support 2 to roll against the inner wall of the reactor 500. During the process of lowering the catalyst loading cloth stabilizing frame 100 inside the reactor 500, the roller 22 rolls on the inner wall of the reactor 500, so as to realize rolling contact of the free end of the foot support 2 with the inner wall of the reactor 500, reduce the rolling friction, and reduce the abrasion of the inner wall of the reactor 500, which is practical.

[0046] Specifically, as shown in Figure 1 , Figure 4 and Figure 5As shown, the foot stool 2 further comprises a telescopic piece 23 and an elastic piece 24. The telescopic piece 23 is movably connected to the end of the foot stool main body 21 away from the hoisting frame 1 and extends from the end of the foot stool main body 21. The roller 22 is rotatably connected to the end of the telescopic piece 23 extending from the foot stool main body 21. The telescopic piece 23 is capable of telescopic movement along the length direction of the foot stool main body 21 to drive the roller 22 to telescopically move. The elastic piece 24 is arranged on the foot stool main body 21 and connected with the telescopic piece 23. The elastic piece 24 is used to generate an elastic force to the telescopic piece 23. The elastic force is directed to the free end of the foot stool 2 along the length direction of the foot stool 2.

[0047] In the embodiment, the roller 22 is telescopically connected with the foot stool main body 21, and the elastic piece 24 is arranged to make the foot stool 2 have a certain telescopic property. The roller 22 at the free end of the foot stool 2 is facilitated to roll on the uneven inner wall of the reactor 500, and the contact between the roller 22 and the inner wall of the reactor 500 can be buffered to effectively reduce the contact stress, avoid damaging the inner wall of the reactor 500, prolong the service life, and have high practicability.

[0048] In a specific embodiment, a mounting groove is arranged in the foot stool main body 21 along the length direction, and the elastic piece 24, for example, a spring, is arranged in the mounting groove. The telescopic piece 23 comprises a telescopic plate clamped on the opposite sides of the foot stool main body 21 and connected with the elastic piece 24. The roller 22 of the foot stool 2 is connected with the foot stool main body 21 in a sandwiched mounting structure.

[0049] Specifically, the catalyst loading and material distribution stabilizing frame 100 further comprises at least three distance detection assemblies (not shown in the figure) arranged at the free ends of the at least three foot stools 2 one by one. The distance detection assemblies are used to detect the distance between the free end of the corresponding foot stool 2 and the inner wall of the reactor 500.

[0050] In the embodiment, the distance detection assembly, for example, a distance measuring sensor, is arranged at the free end of each foot stool 2. The distance detection assembly monitors the distance between the free end of each foot stool 2 and the inner wall of the reactor 500 in real time. When the free end of the foot stool 2 moves to a specified distance position, that is, the free end of the foot stool 2 moves to the inner wall of the reactor 500 and contacts the inner wall of the reactor 500, the control driving mechanism 3 stops working, and the foot stool 2 stops rotating to avoid the contact stress between the free end of the foot stool 2 and the inner wall of the reactor 500 being too large to damage the inner wall of the reactor 500, thereby protecting the inner wall of the reactor 500 and prolonging the service life, and having high practicability.

[0051] In an embodiment, the catalyst loading and material distribution stabilizing frame 100 further comprises a control assembly connected with the distance detection assembly and the driving mechanism 3. The control assembly is used to control the driving mechanism 3 to stop working when the free end of the foot stool 2 moves to the inner wall of the reactor 500.

[0052] Specifically, asFigure 1 As shown, the driving mechanism 3 comprises a driving assembly 31, a moving piece 32 and a connecting piece 33. The driving assembly 31 is installed on the lifting frame 1. The moving piece 32 is connected with the driving assembly 31. The driving assembly 31 can drive the moving piece 32 to move in a direction parallel to the central axis of the lifting frame 1. One end of the connecting piece 33 is hinged with the moving piece 32, and the other end is hinged with the foot support 2. The hinged position of the connecting piece 33 with the foot support 2 is located between the connecting position of the foot support 2 with the lifting frame 1 and the free end.

[0053] In the embodiment, the driving assembly 31 drives the moving piece 32 to move in a direction parallel to the central axis of the lifting frame 1. The moving piece 32 can move linearly to approach or move away from the connecting position of the foot support 2 with the lifting frame 1. When the moving piece 32 moves to approach the connecting position of the foot support 2 with the lifting frame 1, the connecting piece 33 drives the foot support 2 to rotate towards the direction away from the lifting frame 1. The free end of the foot support 2 moves away from the lifting frame 1, so that the catalyst loading and material stabilizing frame 100 is switched to the open state. When the moving piece 32 moves away from the connecting position of the foot support 2 with the lifting frame 1, the connecting piece 33 drives the foot support 2 to rotate towards the direction close to the lifting frame 1. The foot support 2 is folded to the outer circumferential side of the lifting frame 1, so that the catalyst loading and material stabilizing frame 100 is switched to the folded state. The driving mechanism 3 constitutes a linkage structure, which is simple in structure, easy to realize, stable and reliable in work, low in cost and high in practicality.

[0054] Specifically, the driving assembly 31 can be a linear driving device, such as one of a hydraulic rod, a cylinder piston rod, a ball screw and a linear motor.

[0055] In one specific embodiment, the driving assembly 31 comprises a motor 311 and a screw rod 312. The moving piece 32 is a nut. The motor 311 drives the screw rod 312 to rotate, so that the nut moves up and down. The nut is connected with the connecting piece 33, such as a steel frame. The other end of the steel frame is connected with the foot support 2. Through this connection, the motor 311 is driven to rotate to drive the screw rod 312 to rotate. The nut moves up and down to make the foot support 2 contract and expand. The end roller 22 of the foot support 2 is close to the inner wall of the reactor 500.

[0056] In one specific embodiment, the catalyst loading and material stabilizing frame 100 comprises three driving mechanisms 3, i.e., three motors 311, to drive the three foot supports 2 to contract or expand.

[0057] In one specific embodiment, the distance measuring sensor is electrically connected with the motor 311. When the distance measuring sensor detects that the end of the foot support 2 moves to the specified distance position, the motor 311 is powered off.

[0058] On the other hand, as shown in FIG. 6, the foot support 2 is connected with the lifting frame 1 through a connecting rod 4. The connecting rod 4 is connected with the foot support 2 through a hinge 41. The other end of the connecting rod 4 is connected with the lifting frame 1 through a hinge 42. The connecting rod 4 is connected with the lifting frame 1 through a hinge 43. The connecting rod 4 is connected with the lifting frame 1 through a hinge 44. The connecting rod 4 is connected with the lifting frame 1 through a hinge 45. Figure 2As shown, the embodiment of the present application also provides a catalyst distributing device, which comprises the catalyst loading and distributing stabilizing frame 100 provided by any of the above embodiments; the catalyst distributing device further comprises a distributor 300 and a distributing pipeline 200, the distributor 300 is connected to the bottom side of the lifting frame 1 of the catalyst loading and distributing stabilizing frame 100, and the outlet end of the distributing pipeline 200 is connected to the distributor 300.

[0059] In the embodiment, the catalyst loading and distributing stabilizing frame 100 is used to be connected below the hoisting device 400 through the lifting frame 1, so as to hoist and lower the catalyst loading and distributing stabilizing frame 100 in the reactor 500; the distributor 300 is connected below the catalyst loading and distributing stabilizing frame 100, so that the distributor 300 can move up and down in the reactor 500, and the distributing pipeline 200 is used to supply catalyst materials to the distributor 300, so that the distributor 300 can automatically load and distribute materials in the reactor 500. By setting the catalyst loading and distributing stabilizing frame 100 as a foldable structure, the catalyst loading and distributing stabilizing frame 100 can be switched between the folded state and the unfolded state, and the distributor 300 can be stably supported during the process of lowering the catalyst loading and distributing stabilizing frame 100 to a deeper position in the reactor 500, so as to avoid the distributing pipeline 200 swinging violently with the working of the distributor 300, effectively control the stability of the distributing pipeline 200, and thus stabilize the distributor 300 when distributing materials, realize stable distribution, avoid the interference of the swinging of the distributing pipeline 200 on the distribution effect, and more evenly distribute materials, effectively ensure the catalyst loading and distributing effect, and solve the defects in the prior art that the distributing pipeline swings violently with the rotation of the distribution disc, which greatly affects the agent loading effect.

[0060] For example, the distributor 300 is a distribution disc.

[0061] Specifically, as shown in Figure 2 As shown, the distributing pipeline 200 comprises a plurality of telescopic pipes 201, which are connected in sequence along the direction from the inlet end to the outlet end of the distributing pipeline 200, and each of the plurality of telescopic pipes 201 is a rigid pipeline.

[0062] In the embodiment, the cloth pipeline 200 is set as a rigid pipeline to prevent the cloth pipeline 200 from swinging violently with the operation of the distributor 300, further control the stability of the cloth pipeline 200, and play a better stabilizing role when the distributor 300 distributes the cloth, so as to realize stable cloth distribution, avoid interference to the distribution effect caused by the shaking of the cloth pipeline 200, and make the cloth more uniform. Meanwhile, the cloth pipeline 200 is set as an extensible pipeline, the cloth pipeline 200 can be shortened when the cloth distribution starts and ends, so as to save the occupied space, and the cloth pipeline 200 is synchronously lengthened or shortened during the process that the catalyst loading cloth stable frame 100 is lowered or raised by the hoisting device 400, so as to be simple and convenient to use and have high practicability.

[0063] Specifically, the diameters of the multiple extensible pipelines 201 gradually increase from the inlet end to the outlet end of the cloth pipeline 200.

[0064] In the embodiment, the diameters of the multiple extensible pipelines 201 gradually increase from the inlet end to the outlet end of the cloth pipeline 200, that is, the inner diameter of the cloth pipeline 200 gradually increases from the inlet end to the outlet end, so as to form an expanding pipeline, ensure that the catalyst material does not accumulate in the cloth pipeline 200, improve the catalyst loading efficiency, and ensure the catalyst loading effect.

[0065] Specifically, as shown in Figure 6 The cloth pipeline 200 further includes a funnel 202, the funnel 202 is connected to the outlet end of the cloth pipeline 200, and the outlet inner diameter of the funnel 202 is the same as the inlet inner diameter of the extensible pipeline 201 at the inlet end of the cloth pipeline 200.

[0066] In the embodiment, the funnel 202 is arranged at the outlet end at the lowermost position of the cloth pipeline 200, the outlet diameter of the funnel 202 is the same as the inlet inner diameter of the inlet end at the uppermost position of the cloth pipeline 200, that is, a contraction pipeline is formed in the funnel 202, the falling catalyst material can be buffered, so that the catalyst material is more concentratedly dropped into the distributor 300 below, the loading efficiency and the loading density are improved, and the loading effect is better.

[0067] Specifically, as shown in Figures 7-9 The end of the extensible pipeline 201 close to the inlet end of the cloth pipeline 200 is provided with a limiting ring 203, and the limiting ring 203 is used to pass through the flexible traction member 401 of the hoisting device 400.

[0068] In the embodiment, the hoisting device 400 comprises a flexible traction member 401, such as a steel cable, which is connected with the hoisting frame 1 to hoist the catalyst loading and cloth stabilizing frame 100 on the hoisting device 400, and the hoisting device 400 winds or unwinds the flexible traction member 401 to drive the catalyst loading and cloth stabilizing frame 100 to move up and down. During the hoisting of the catalyst loading and cloth stabilizing frame 100 by the hoisting device 400, the cloth pipeline 200 is synchronously elongated or shortened with the flexible traction member 401. The flexible traction member 401 passes through the limiting ring 203 from the inside of the limiting ring 203, which is arranged on the outer periphery of each telescopic pipe 201 close to the inlet end, so as to limit and guide the flexible traction member 401 and prevent the cloth pipeline 200 from being stuck during the telescopic movement, thereby improving the safety of the catalyst loading operation.

[0069] In one embodiment, the limiting ring 203 comprises a fixed part 204 and a movable part 205. The fixed part 204 is fixedly connected to the outer side wall of the telescopic pipe 201, and the movable part 205 is movably connected with the fixed part 204. The movable part 205 can rotate relative to the fixed part 204 about an axis parallel to the telescopic pipe 201 to rotate close to or away from the outer side wall of the telescopic pipe 201. When the movable part 205 rotates close to the outer side wall of the telescopic pipe 201, the fixed part 204 and the movable part 205 form a closed limiting ring 203. When the movable part 205 rotates away from the outer side wall of the telescopic pipe 201, the limiting ring 203 is opened to pass the flexible traction member 401 into or out of the limiting ring 203.

[0070] Specifically, the outer periphery of the telescopic pipe 201 is provided with a plurality of limiting rings 203, and the plurality of limiting rings 203 are arranged at uniform angles around the outer periphery of the telescopic pipe 201.
